Tying "filters" and "order by" to proper shape object

[Pentusha]

Query that could not be expressed with current state of query builder:

select User {
    friends: {
        name
    } FILTER .name = User.name
}

That's how edgedb-js solves this issue:

e.select(e.User, (user) => ({
   friends: (friend) => ({
      name: true,
      filter: e.op(friend.name, "=", user.name)
   })
}))

It creates a new closure using anonymous functions. Not sure that it is the good solution for python.
